[tbb-dev] Last changes pushed to tor-browser-build.git will require rebuilding everything

Hello,

The MR tor-browser-build!579 has just been merged to main and maint-12.0. It includes some changes that will cause everything to be rebuilt, so if you have been building tor-browser before and are not planning to rebuild old versions (or branches based on old commits), it is a good time to remove the `out` directory as most files in there are not going to be used for new builds.
